This is Moneyball: What's the true cost of becoming a tennis pro? Marcus Willis reveals all

It's that time of year again – Wimbledon, arguably the best tennis tournament in the world, starts next week. Assistant editor Lee Boyce and broadcaster Georgie Frost dust off their picnic blankets, pack the strawberries and cream and talk tennis with British pro – and plucky underdog – Marcus Willis, who has been ranked as high as 209th in the world. We look at the state of the game in Britain and why more youngsters are heading to the US, including 19 year-old Paul Jubb, a Wimbledon wildcard entry who may have to reject his £45,000 cheque. We discuss life after Andy and the true financial cost of training a child up to become a top tennis player – and the physical and mental cost to boot. Marcus also reveals all about his truly remarkable run in Wimbledon in 2016 in which he played Roger Federer on centre court – and managed to lob the best tennis player in history. He also reveals how much money that summer made him and how bonkers life became after he was thrust in the spotlight.
